Mitsubishi Electric FR-F800 Series Instruction Manual page 447

• The pre-charge function valid/invalid settings and pre-charge ending conditions are as follows:
Pr.127 setting
Pr.761 setting
9999 —
9999
Other than
9999
Other than 9999
*1 When two or more ends conditions are satisfied, the pre-charge operation ends by the first-satisfied condition.
NOTE
• During the pre-charge operation, it is regarded as integrated value = estimated value. The motor speed may drop shortly from
the automatic switchover frequency depending on the parameter settings.
• Parameter changes and switchover to the second PID control are applied immediately. If PID control has not started when the
settings were changed, PID control starts with changed settings. (If PID control has already started, these settings do not
apply. If the changed settings already satisfies a condition to start PID control, the PID control starts as soon as these are
changed.)
• The pre-charge also ends when PID control is set to invalid, the start command has been turned OFF, and output has been
shut off.
